Chinese test equipment: What is used inside

[Scratch.HTF]

From what I can see, Hantek uses the following in current (at the time of posting) models of test equipment: Samsung SOCs, Micron DRAM, Xilinx programmable logic, Cypress high speed USB microcontrollers, Texas Instruments DC-DC converters, Analog Devices high speed ADCs/DACs and clock generators (some short memory AWGs may use Burr-Brown (TI) high speed DACs).
So therefore, I am curious on what SOCs/DRAM/programmable logic/high speed USB microcontrollers/DC-DC converters/high speed clock generators and high speed ADCs/DACs are used by current model Chinese test equipment including from Siglent, Rigol, Owon, Uni-T, Atten, and Micsig.
